PATENT MIXING VALVE.

Application mediAprn 11, 1924. semi No. 705,884.

To all whom, t may concern:

Be it known that ll, CLARENCE C. HICK- nnsoN. a citizen ol`l the UnitedStates, residing at Tulsa, in the county of .Tulsa and State ofOklahoma, have invented new and useful mprovements in Mixing Valves, ofwhich the following is a specilication.

This invention relates to water distribution apparatus, particularly tovalves, and has for its object the provision of a' novel valve designedparticularly for use in connection With shower baths or for otherpurposes, whereby hot and cold water may be mixed in the desiredproportions.

An additional object is the provision of a device of thischaracter whichwill be simle and inexpensive in manufacture, neat -and attractive inappearance, eilicient and durable in serviceand a general improvement inthe art.

With the above and other objects and ladvantages in view the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, in

which:

Figure 1 is 'a longitudinal section through a valve constructed inaccordance with my invention, f

Figurey2 is a plan view, I

Fi re 3 is a cross section on the line 3-3 of Flgure 1.

Referring more particularly to the drawings I have shown the valve ascomprisinga hollow body :formed at its lower portion with oppositelyextending branches 11 and 12 to which are connected hot and cold waterconduit pipes, not shown. rIfhese branches are internally threaded asshown for connection with the pipes therewith. These branches of coursecommunicate with the interior of the body through the ports 13 and 14respectively. Internally the hollow body is provided at its intermediateportion with an upstanding flange 15 which constitutes a valve seat, andabove this ange the' body is formed wlth an outlet port 16 leading into.a threaded branch 17 to which an outlet pipe` may be connected. u

At its up er end the body is formed with an outstan ing flange 18 onwhich is 'secured, as by screws 19, a cover plate 20 having a centralhub portion 21 formed with a thread 22 of steep pitch. The hub ex-'ltends above the cover plate and is externally threaded for engagementthereon of a cap 23 filled vwith packing 23.' It should be mentionedthat there is a gasket 24' of suitable material interposed between theflange 18 On the 00 and the cover to'prevent leakage. upper end of thehub within the cap 23 are metal washers 25 which` prevent the packing inthe space above from being compressed againost thethread 22.

Rotatably mounted fitting within the lower portion of the hollow body isa cylindrical sleeve valve 26 carriedbya stem 27 which extends throughand beyondthe cap 23 and which is equipped 'with an operating handle 28.rlhe 70 stem 27 carries an enlargement 29 which is threaded forco'-operation with the threads 22 so that when the handle is turned, thevalve 26 will be moved longitudinally `as well as rotatably. p the valve26 is formed with two openings 30 and 31 adapted to be broughtselectively into registration with the ports 13 and 14. The top 'of thesleeve valve 26 is closed by a wall 32 from which flanoe 33 which 1schanneled and which holrs a gasket 34 adapted to seat compressingly uponthe flange 15 for cutting oil' flow of water through the device. Withinthe confines of the flange 15 is an angular cham- 35 ber 34a which.communicates with the interior of the sleeve 26 through a plurality ofholes 35.

In the operation, it is apparent that, as-

suming the valve to be closed as 'shown in 90 Figure 1, to obtain asupply of water it is necessary to turn the handle 28 in aconterclockwise direction, whereupon the co-acting threads will providelongitudinal movement of the valve so that it will disengage 95 theflange `15. At the same time, thel open-- ing will be brought partially,and theny entirelyinto registration with the port 13, permitting waterto enter the sleeve 26 and pass through the holes into the chamber 10034 and out into the body and thence through the outlet branch 17. Byproperly manipulating the valve, it is apparent that either opening 30or 31 may be brought into registration with the desired port 13 or 14105 and conformingly The bottom portion of rojects an outstanding S0 Byturning the handle in a clockwise direction the quick acting thread willcause the iange 33 to reseat' upon the dang@ l5 for cutting o thesupply. v

v `While l have shown and described the pre-Y erred embodiment of myinvention it is of coursel to vhe understood that l reserve the rightptomake such changes in the form, construction" and arrangement of parts aswill not depart from the spirit of the invention Aor the scope of theAsubjoined claim.

l.v In a device of the character described comprising a'hollovv bodyp'rovided in one side near one end with a pair of inlets, and providednear its otherA end withan outlet a chamber within the first mentionedend of the body, a Hangs within the body constituting a valve seat, theinternal diameter of the l@deluge being greater than that 'of the cham-;{cer todene an annular space, a cover closing the other end of the bodand having a central hub rtion forme with a. steep thread, a cylindricalsleeve valve rotatable i within thel chamber and having openingsadaptedto register selectively with said inlets and having anoutstanding liange carryinge gasket adapted to engage upon said seat forcutting oi the How, the valve having a plurality y of holescommunicating with. said annular space, a stem'on the valve ex-l4tendingl beyond the cover and equipped with
